7. First Usage - Quick Start
Connect the TRS-jacks or the XLR connectors with the analog signal source. The input sensitiv-
ity of the rear inputs can be changed in the Settings dialog (Input Level), assuring the highest
signal to noise ratio will be achieved. Try to achieve an optimum input level by adjusting the
source itself. Raise the source’s output level until the level meters in TotalMix reach about –3
dB.
The analog line inputs of the Fireface 800 can be used with +4 dBu and -10 dBV signals. The
electronic input stage can handle balanced (XLR, TRS jacks) and unbalanced (TS jacks) input
signals correctly.
The front inputs signal level can be optimized using the Fireface's Gain pots. A Signal LED and
a Clip LED help to find the correct level adjustment.
The Fireface's digital outputs provide SPDIF (AES/EBU compatible) and ADAT optical signals
at the corresponding ports.
On the analog playback side (the DA side), a coarse adjustment of the analog output level at
the rear jacks is available in the Settings dialog (Output Level).
The output signals of channels 9/10 is available on the front. Their output level can be set using
the VOL pot. This output is a very low impedance type, which can also be used to connect
headphones.
The function Store in Flash Memory (Settings dialog) and Flash current mixer state (TotalMix)
allow to store the current settings into the Fireface 800. The unit then remembers all settings,
and loads these automatically when switched on. With this, the Fireface 800 can be used
stand-alone after setting it up accordingly, replacing lots of dedicated devices (see chapter 13).
